MOUNTING FOR PHONOGRAPH MOTORS.. fr 1 Application led. May 1,

To all .whom t may concern:

Be it known that I, CLINTON E. WooDs, a citizen of the United States,residing at lVaterbury, county of New Haven, and State of Connecticut,have invented certain new and useful'mprovements in Mountings forPhonograph Motors, fully described and represented in the followingspecification and the accompanyingdrawings, forming a part of the same.Y

This invention relates to phonographs and particularly to the mountingvfor the motor mechanism.

In the usual phonograph construction, the

turntable is mounted on a motor driven spindle to rotate above a cabinetshelf, on which is mounted the stopping brake and other parts. AIn orderthat the brake memf ber may properly align with the edge of theturntable, the latter should have' a given elevation above the cabinetshelf. With heretofore known methods of mounting the motor in thecabinet, the given elevation` of the turntable was not alwaysmaintained, as the cabinet shelves vary in thickness, by warping and thelike.

It is the principal object ofthe present invention to provide aphonograph construction such that the turntable may always have a givenelevation above the cabinet shelf.

It isa further object of the invention to provide a compact,convenientlyassembled motor unit that may readily be mounted in readymade cabinets to fulfill the conditions above mentioned, without thenecessity of carefully positioning and adjusting the parts of eachmachine.

lVith these general objects in View, the invention consists in thecombinations, details of construction and arrangements of parts whichwill first be described in connection with the accompanying drawing andthen more particularly pointed out.

In the drawing,

Figure 1 is a view, partly in vertical' section, and partly inelevation, of a portion of a phonograph constructed in accordance withthe invention.

Figure-2 is a similar view taken on a section at right angles to that ofFig. 1; and

Fig. 3 is a. similar view, with partsremoved, taken on a differentsection.

Referring to the drawing there is provided a cabinet shelf, eXemplied atll, l1av- 19.20, serial No. 378,033.

ing a circularopening 12 formed therein.`

vThe,inventionincludes a motor vmechanism including a turntable spindle,and means .for

so supportingl the 'motor V'mechanism fromy the cabinet shelf that thespindle 4will have a givenfprojection above the shelfVA regardless ofthe thickness of the latter.' rlfhis may be accomplished, for example,by suspend- Y ing a base plate from the top ofgthecabinet Shelf andsupporting the motor mechanism entirely vbyvbearings carriedfby the.base plate. l

Although capable of various construel tionsin that shown, there isvprovided'a base plate 13 having a bottom rib 14-to which is attacheda'housing 15. by the base plate are bearings forr the motor 1 CarriedjvpartsY and in structures embodying., the in`l vention to the bestadvantage, two` bearingsa-re provided, one being cast integral with thebase plate, the other. being separate. As

Depending lfrom the base plate and cast:

integral therewith is a second bearing bracket 24. Journaled in thisbearing and in a boss 25 in the base plate through which it extends, isthe turntable spindle 26. For part of its length the spindle is formedwith worm teeth 27 meshing with a worm gear 27. The latteris mounted ona stud 28 driven by a pinion 29 which meshes in turn with the springdriven gear 23. The spindle has mounted thereon a gear 30 for driving acentrifugal governor of any suitable construction, indicated generallyby 31,

The parts are so dimensioned that the housing 15 has an easy fit inside'the open#v ing 12 in the cabinet shelf. The base plate 13 extends outbeyond the rib 14 to havey a flange like portion 33 which is substanftially greater in diameter t-han the opening in the shelf 11. Below theange 33 is a seating gasket 34 which, for present purposes, may beconsidered as partof the base plate.
